The leasing office tells me that they have people calling asking for 3-month summer leases already. So, they make no guarantees, but they say they'll help hook you up with a lease transfer for the summer as best they can.

Also, it's not subletting, it's lease transferring. The benefit is there's no risk to you, they pay their own security deposit, etc. Also, the person you transfer to doesn't (in most cases) live in your room with your roommates. So, you can transfer to a total stranger and Lorenzo will handle pairing them with compatible roommates.
